The purpose of this paper is to study the self-similar properties of discrete-time long memory processes. We apply our results to specific processes such as GARMA processes and GIGARCH processes, heteroscedastic models and the processes with switches and jumps.

This paper investigates hot money inflows in China. The financial liberalization comes into effect and the effectiveness of capital controls tends to diminish over time. As a result, China is fuelled by hot money inflows. The US interest rate cut since 2001 and expectations of exchange rate...

This paper examines causality between the series of returns ans transaction volumes in high frequency data. The dynamics in both series is restricted to transitions between a finite umber of stated. Depending on the state selection criteria, this approach approximated the dynamics of varying...

The Yule-Walker estimator is commonly used in time-series analysis, as a simple way to estimate the coefficients of an autoregressive process. Under strong assumptions on the noise process (i.i.d. or martingale difference), this estimator possesses the same asymptotic properties as the Gaussian...

This paper studies a classical extension of the Black and Scholes model for option pricing, often known as the Hull and White model. Our specificity is that the volatility process is assumed not only to be stochastic, but also to have long memory features and properties.

The classical definition of GARCH-type processes rely on strong assumptions on the first two conditional moments. The common practice in empirical studies, however, has been to test for GARCH by detecting serial correlations in the squared regression errors. This can be problematic since such...

We use Backus and Kehoe (1992) long, low frequency data on real GNP/GDP and money for Australia, Canada, Denmark, Germany, Italy, Japan, Norway, Sweden, the United Kingdom and the Uniter States to examine the long-run neutrality and superneutrality of money propositions. In doing so, we apply...

We study the reliability of the estimated responses of major economic aggregates to monetary policy shocks. We investigate the bias of the estimated impulse response functions and the reliability of their qualitative features such as their sign and shape and the timing of peaks and troughs. We...
